As a management consultant, I have often been hired to help with Business plans. (As an entrepreneur, I've also written a few of my own.) But if you hire someone, it still needs to be "your" plan. Nobody can go away and write it for you.

It needs to reflect the entrepreneur's passion, competence, knowledge and commitment to the business. A consultant can help with the planning process, words, numbers, and presentation, but investors, lenders and strategic partners need to know the entrepreneur behind the plan, not the consultant.
